HI guys/gals,

Currently 2013 dodge challenger RT classic 5.7 with magnusson supercharger tvs 2300.

Very close on upgrading to Large block 426 stroker 7.0 L.

The question i have when buying parts API Competition Single Pump Fuel System from Shop Hemi website, should i buy the kit for 6.4 or still stick with 5.7 ? Will the pump fit i i buy 6.4 or does the fuel pump have nothing to do ( connections wise ) from a 5.7 or 6.4 engine ?

As for drivetrain upgrade, that i know i will need to get a 6.4 drivetrain correct ?
